Welcome to the TISN website

Critical infrastructure delivers essential services such as food, water, healthcare, electricity, communications, transportation and banking. Without these services, Australia's social cohesion, economic prosperity and public safety are threatened. The resilience of our critical infrastructure is therefore integral to a strong economy and a vibrant business sector. It is also vital to the resilience of our communities to disasters.

The Trusted Information Sharing Network (TISN) for Critical Infrastructure Resilience was established by the Australian Government in 2003. It is Australia's primary national engagement mechanism for business-government information sharing and resilience building initiatives on critical infrastructure resilience. The TISN provides a secure environment for critical infrastructure owners and operators across eight sector groups to regularly share information and cooperate within and across sectors to address security and business continuity challenges.

The work of the TISN is also complemented by a range of business-government engagement mechanisms on broader national security policy issues.

Australian Government Critical Infrastructure Resilience Strategy

The Attorney-General, Senator the Hon George Brandis QC launched the Critical Infrastructure Resilience Strategy in May 2015. The strategy consists of a policy statement and a plan for practical implementation, and aims to ensure the continued operation of critical infrastructure in the face of all hazards.
